Jokes about breasts, and men looking at breasts, are such a comedy staple they’ve become a kind of go-to cliché. How many times have we seen a man talking to a curvaceous woman only to have her point to her own eyes and say “Hey, buddy, up here!”?

It’s funny — or, at least, it was funny the first dozen times we saw it — because it’s true. The male eye does have a way of drifting south. But why? Why are heterosexual men so fascinated by women’s breasts that we sometimes act as if the breasts are the seat of the soul?

Well, we happen to be heterosexual men. We also happen to be men interested in biology — one of us, Larry, is one of the world’s leading experts in the neuroscience of social bonding. So we’ve been thinking about this, and, in our new book, The Chemistry Between Us: Love, Sex, and the Science of Attraction, we propose an answer.

Biologically speaking, this human male breast obsession is pretty weird. Men are the only male mammals fascinated by breasts in a sexual context. Women are the only female mammals whose breasts become enlarged at puberty, independent of pregnancy. We are also the only species in which males caress, massage and even orally stimulate the female breasts during foreplay and sex.

Women do seem to enjoy the attention, at least at the right moments. When Roy Levin, of the University of Sheffield, and Cindy Meston, of the University of Texas, polled 301 people — including 153 women — they found that stimulating the breasts or nipples enhanced sexual arousal in about 82 percent of the women. Nearly 60 percent explicitly asked to have their nipples touched.

Men are generally pretty happy to oblige. As the success of Hooters, “men’s” magazines, a kajillion websites, and about 10,000 years of art tell us, men are extremely drawn to breasts, and not because boys learn on the playground that breasts are something that they should be interested in. It’s biological and deeply engrained in our brain. In fact, research indicates that when we’re confronted with breasts, or even breast-related stimuli, like bras, we’ll start making bad decisions (and not just to eat at Hooters).

For example, in one study, men were offered money payouts. They could have a few Euros right away, or, if they agreed to wait a few days, more Euros later. In this version of a classic “delayed gratification” (also called intertemporal choice by behavioral economists) experiment, some men watched videos of pastoral scenes while others watched videos of attractive women with lots of skin exposed running in slo-mo, “Baywatch” style. The men who watched the women’s breasts doing what women’s breasts do opted for the smaller-sooner payouts significantly more often then men who watched the pastoral scene.

This likely indicates that parts of their brains associated with “reward,” the pleasure centers, and the sites of goal-directed motivation, were shouting down the reasoning centers of their brains, primarily the pre-frontal cortex. Neurochemicals were activating those reward and motivational circuits to drive men toward taking the short money.

So breasts are mighty tempting. But what purpose could this possibly serve?

Some evolutionary biologists have suggested that full breasts store needed fat, which, in turn, signals to a man that a woman is in good health and therefore a top-notch prospect to bear and raise children. But men aren’t known for being particularly choosy about sex partners. After all, sperm is cheap. Since we don’t get pregnant, and bear children, it doesn’t cost us much to spread it around. If the main goal of sex — evolutionarily speaking — is to pass along one’s genes, it would make more sense to have sex with as many women as possible, regardless of whether or not they looked like last month’s Playmate.

Another hypothesis is based on the idea that most primates have sex with the male entering from behind. This may explain why some female monkeys display elaborate rear-end advertising. In humans, goes the argument, breasts became larger to mimic the contours of a woman’s rear.

We think both of these explanations are bunk! Rather, there’s only one neurological explanation, and it has to do with brain mechanisms that promote the powerful bond of a mother to her infant.

When a woman gives birth, her newborn will engage in some pretty elaborate manipulations of its mother’s breasts. This stimulation sends signals along nerves and into the brain. There, the signals trigger the release of a neurochemical called oxytocin from the brain’s hypothalamus. This oxytocin release eventually stimulates smooth muscles in a woman’s breasts to eject milk, making it available to her nursing baby.

But oxytocin release has other effects, too. When released at the baby’s instigation, the attention of the mother focuses on her baby. The infant becomes the most important thing in the world. Oxytocin, acting in concert with dopamine, also helps imprint the newborn’s face, smell and sounds in the mother’s reward circuitry, making nursing and nurturing a feel-good experience, motivating her to keep doing it and forging the mother-infant bond. This bond is not only the most beautiful of all social bonds, it can also be the most enduring, lasting a lifetime.

Another human oddity is that we’re among the very rare animals that have sex face-to-face, looking into each other’s eyes. We believe this quirk of human sexuality has evolved to exploit the ancient mother-infant bonding brain circuitry as a way to help form bonds between lovers.

When a partner touches, massages or nibbles a woman’s breasts, it sparks the same series of brain events as nursing. Oxytocin focuses the brain’s attention to the partner’s face, smell, and voice. The combination of oxytocin release from breast stimulation, and the surge of dopamine from the excitement of foreplay and face-to-face sex, help create an association of the lover’s face and eyes with the pleasurable feelings, building a bond in the women’s brain.

So joke all you want, but our fascination with your breasts, far from being creepy, is an unconscious evolutionary drive prompting us to activate powerful bonding circuits that help create a loving, nurturing bond.

We all know the saying “bigger is better” and apparently that rings true in regards to breast size. No one should seem all that shocked considering society has always seen that the majority of men find larger breasts more appealing. And now there is plenty of research that proves this is true. This article will discuss why men like big breasts.

In New Zealand, one research project tracked the movement of men’s eyes when they were conversing with women. The found that men who were speaking to women with small to medium-sized breasts were better able to maintain eye contact. However, when men spoke to women with larger breasts, their eyes would shift from the women’s eyes to her breasts throughout the conversation.

One French study had several different women wear different sized padded bras. They were instructed to sit alone in a café. The study showed that women who were wearing the larger padded bras were approached more by men.

So what exactly does this mean? The research conducted suggests that society’s long-held belief that men prefer larger breasts is true. Even dating back to nearly 35,000 years ago, people had been creating cave art of women with voluptuous hips and breasts. Biologically speaking, women with greater breast size are instinctively viewed as better able to provide for offspring. So if men say they prefer women with larger breasts, but aren’t able to offer an explanation as to why, that is the reason for their preference.

Are you thinking about breast implants? There are many reasons why women go in for breast implants, some of them medical and others purely aesthetic. We all want to love our bodies the way we are but sometimes, our inner vision and our outer appearance don’t exactly match. This is why some women get breast implants.

Sometimes, we want to fit into our clothes better. At other times, we just want to feel better about ourselves. And sometimes, we want to appear more attractive to the opposite sex. These are all good reasons to get breast implants.

DoYou Want to Get Breast Implants?

The most important thing you should ask yourself before going in for this procedure is: Do I want breast implants? Do you really think that you would feel better if you had breast implants or are you just doing it to please someone else? It’s a good idea to go in for this procedure if you really feel that it’s best for you and not because someone else recommends it.

How Big Do You Want to Go?

The second question you might want to ask yourself is how big you want to go. Do you really feel that you need to get breasts as big as those of porn stars? Are you not going to be happy unless you have double Ds? Or do you just need to go up by a size or two?

You should also take the general proportions of your body into consideration before you get implants. If you’re generally a very slim person, then you might not want to get breasts which are very big or else you’ll look too top-heavy. If you have a sizable derriere, you can probably get away with very large-sized breasts.

Wardrobe Changes After Getting Breast Implants

Remember that once you get implants, you’ll have to change your wardrobe and the way you dress. Some small-breasted women can get away with going braless but this won’t be an option with anything larger than a B cup.

Plus, when you have bigger breasts, you have to get well-tailored clothes to make sure that you are showing just the right amount of cleavage. Many ready-made clothes are geared towards slimmer women these days, just because that’s the way the fashion industry works. So you might find many dresses ride up a bit higher when you have larger breasts. You might need to stop going to stores geared towards younger women, like Forever 21 or Express and go to stores geared towards older women like Ann Taylor or stores which stock more clothes for curvy women like Bebe.

If you really want to get breast implants, none of these is going to be a deterrent for you. And if you’ve always felt like a large-breasted woman in a small-breasted woman’s body, you should definitely go for breast implants. Just keep in mind all the lifestyle changes you might need to make when you do this.
